What Are OTPs in Messaging?
Systems auto-generate a temporary code, referred to as a One-Time Password (OTP), to secure online transactions and protect logins. In the case of messages, the system usually delivers them to your phone either as SMS or within the app for OTP.
- In short: What are OTPs in messaging? The system sends security codes via phone number or email to confirm an action or identity, and users can use them only once.
Why OTPs Are Essential for Online Security
By knowing what OTPs are in messaging, you can guard your accounts more effectively. 2FA creates an additional security layer to your password by utilizing OTPs.
Key Benefits of OTPs:

How OTPs Work in Messaging

Once you use the code, it becomes time-sensitive and loses its usefulness, which is what makes it a one-time password.
Common OTP Delivery Methods:
- SMS OTPs: Text message OTPs
- Email OTPs: You must do it through the email you registered with
- Authenticator Apps: The device (e.g., Google Authenticator) creates OTPs.
- Push Notifications: App services could offer these.
